THERMO-ELECTRIC GENERATOR.-

s rxcmcanon formingpart of Letters Patent No. 635,490, dated March 12,1895. Application fled arms a, ma. Renewed August 14, 1894." smn No.520,330. (so model.) I

To all whom it may concern:

Be it known that I, HARRY BARRINGER Cox, of Hartford, in the county ofHartford and .State of Connecticut, have invented certain new and nsefulImprovements in Thermo- Electric Generators; and I do hereby declarethat the followingisafull, clear, apdexact description of the invention,which will enable othersskilled in the-artto which it appertaius retoshe and use thesame, reference being the accompanying drawings,-andtothe 'letters of reference marked thereon, which form part of thisspecification. This invention relates to certain improve- :5 meats inthermo electrlc generators.

- The object of the invention isio provide in an improved manner therm'oelectric piles with radiators whereby the potential in the circuit willbe increased The invention consists in certain uovel'featnres ofconstruction and in combinations of parts more fully describedhereinafter and particularly pointed out in the claims.

Referringtotheaccompgnyiriidrawirigsr- 2 5 F gure 1 is a cross sectionof a therrno electric pile. Fig. 2 is adetail sectional view of amodification.

In the drawings'the reference letter a, indicatfsa serieaxgficourfieotgili tihersno electric coup r .connec' re era y n r ugf rzruannmb'er of rings oing placed. togetner to form a pile i open-orcylindrical form. The heat is app'ied .to the interior-of the pile. The.rings after being suitably secured'together, preferably contact at theirinner andont'erends. with some suitablefire 'proofmateriaigsuchasfireclay gvhichisthenbalred, hardened or vitrified to arma hard coating b on the inner and ontert'aces of the pile. The cutesurface of this hard cylinder is then pro tried in some suitable mannerwith a meta to acket 0. The outer ends of the thermo Jacket.

In Fig. 2 the radiators are formed byacorelements are the cool portionsof the circuit while the inner ends thereof constitute the head portionsof the circuit. In order to 1ncrease the difference intenip'eraturebetween the inner and outer snrfa'ces'of the pile, theouter surface of/the pileor generator is provided with suitableoutwardly projecting radiators (1. These radiators preferably extend outfrom the outer metallic jacket of the pile,

and rapidly'couductoif the heat from'thepila I do not wish to limitmyself to any peculiar construction of radiator or any peculiar mannerof arranging or connecting-the same.

Iu-Fig. 1, the radiators shown consist of. U shaped strips of metalsuitably secured at theirbent ends to the metallic jacket so thatthelegs of the U project radially from said 6 rngated strip of metalsecured around the pile so that the corrugations project outwardly andradially from the pile., Having thus fully described myinvention, what Idesire to secure by Letters Patent of the United States isp a 1. Athermo electric pile provided with the outwardly projecting radiatorsfrom its outer surface independent of the elements of the thermocouples, substantially as described.-

2. A thermo electric lpile having the exterior metal jacketand theseries of radiators extending outwardly therefrom, substantially asdescribed. 3. A thermo electric generator having the exterior coatingand the exterior radiators,- substantially as described. a t

In testimony that I claim the foregoing as my own I a'ffix my signaturein presence of 8c two witnesses.
